Edit: Turns out it’s not the fault of v1.62.1. Details below.
Original Post
Bad news for v1.62.1. I just compiled my project with the new version and it’s become unusable. Framerate has severely dropped; around 50% from a first view. Similarly, page loading time pretty much doubled from 1 to 2 seconds.
Maybe even worse, the serial coms are completely hit and miss. Half of the commands fail. Either no response at all from Nextion, or 0x1a (invalid variable), or 0x00 (instruction failed). I can’t even update the firmware with the upload function from the editor because it doesn’t even connect 9/10 times. And the one other time it just gets stuck at 1% - probably because Nextion doesn’t acknowledge. Honestly, at that point I couldn’t be bothered investigating it.
I haven’t done any precise benchmark tests yet, so no “hard facts” I could provide, but the difference is obvious enough without.
Can anyone confirm those observations?
Technical details:
- NX8048T050 (5" Basic) screen
- Communication baud rate: 115200baud/s (Upload baud rate - if it had ever uploaded something: 512000baud/s)
- Serial data probed with an RTB2004 scope to rule out every possible cause outside of the Nextion touch screen. Thus I can confirm that indeed, correct commands went to the screen.
- Last known 100% working version: 1.61.1. None of the issues described above ever happened with that one.
Kind regards,
Max
